Shandora is the ancient city that resided on Jaya, but was later blasted up to Upper Yard by the Knock Up Stream. It was known as the "City of Gold" (黄金都市, Ōgon Toshi). Shandora literally means "the skull's right eye" which refers to its location on the skull shaped island.
Shandora was built 1100 years ago by the Shandorians, the ancestors of the Shandia. During the Void Century, Shandora fell to the Twenty Kingdoms that would soon become the World Government. The Shandia fought to protect their poneglyph. After the Void Century, Shandora crumbled to ruins but the Shandia continued to guard the city.
